Crack Machine Designs

I want to put some type of crack machine(s) in the garage for the Winter and would love suggestions on which types of designs have worked for you, and where to find them online or otherwise. I think a horizontal design would work a little better for the space, but am open to a vertical setup as well. 

Thanks

This is the most economical crack machine that I've ever seen. Not nearly as cool as a home made roof crack though.

I do believe it's just texture'd paint. That isn't my exact machine. I found that photo online and am in the process of re-creating one for myself.

I would guess epoxy, although maybe you could use cheap wedge bolts and a hammer drill to bolt the blocks to the wood.

I built it with 2x10s and cultured stone-bull nose that wraps around the edge of the 2x.  I got the cultured stone essentially for free at a used building material place (Uncle Benny's in Loveland) because I traded some other materials for it.
I used about $75 worth of PL Premium 3x in the larger 30 ounce tubes.  The manufacturer recommended to wet both surfaces before gluing and to use pressure while the glue is drying.  I used heavy weights for this (cinder blocks and weight plates).  
It is held together with all thread and nuts, so it is adjustable.  I added angle iron on the sides to stiffen it.
